From: Conformation and physics of polymer chains: a single-molecule perspective
Diffusion of labeled linear (top) and cyclic (bottom) polymer chains in semi-dilute solution of unlabeled linear chains of the same polymer. (a) Linear and cyclic poly(tetrahydrofuran) (PTHF) molecules containing a perylene diimide (PDI) moiety. (b) Configuration of PDI–linear PTHF and PDI–cyclic PTHF surrounded by linear PTHF. (c) Two-dimensional trajectories of self-diffusing molecules of PDI–linear PTHF and PDI–cyclic PTHF. (d) Histograms of diffusion coefficients for PDI-linear PTHF and PDI-cyclic PTHF. Lines show calculated theoretical statistical distributions corresponding to the diffusion of single molecules in a homogeneous environment using the diffusion coefficients from the respective histograms.
